AVK Valves have introduced a new gate valve with up- and downstream purge points. The valve is based on the renowned AVK series 46 design with long steel spigot ends for gas applications. The purge pipes welded on the top of the valve spigot ends are leading towards the top of the valve and are assembled with CE approved ball valves and blind flanges.
The purge points make it possible to purge residual gas in an isolated pipeline section allowing safe maintenance, repair or extension of the pipe system; by-pass the isolated section to ensure continuous gas supply; and detect leakages in the pipeline by measuring the pressure by means of pressure gauges.
The valves are as standard with external PUR coating and will be available in DN80-600.
